IMPROVEMENT IN CREASING DEVICES FOR TRACES, &c.

Specification forming part oi' Letters Patent No. 129,123, dated July16, 1872.

To all whom it may concern Be it known that I, HOWARD S. FoUsT, ofWilmot, in the county of Stark and State of Ohio, have invented anImproved Oreasing Instrument for harness-traces and straps of leather;and I do hereby declare that the following is a full and exactdescription thereof', reference being had to the accompanying drawingmaking part of this specification- Figure l being a top view ot' thedie, showing one form of molding or creasing; Fig. 2, a side view of thecreasing-tool, shaped to go with the die 5 Fig. 3, a cross-section ofthe die and of a harness-trace being creased therein, and a front Viewof the creasing-tool in position for operation in the die; Fig. 4, acrosssection of a finished trace creased in the die.

Like letters designate corresponding parts in all of the figures.

The die A is made from wood or other suitable material, and has alongitudinal groove, a, therein, of the form to produce the creasing' orshaping of the trace or other strap placed therein. It is of suflicientlength to contain so much ofthe trace or strap as is required to beoperated on at once, and need not be any longer. The creasing-tool B hasa form of shaping end b to be the counterpart of the cross-section ofthe die A, as indicated in Fig. 3, and it is of proper lengthand size tohold in the hand. The molded end b also is rounded in side view, asshown, so that it will bear tangentially in whatever position heldapproximating to the vertical, thereby requiring no particular accuracyin holding. Its whole width is just sulcient to fit and run closelybetween the sides of the molding-groove in the die A, which serve asguides for that purpose, being high enough to keep the tool in placewhen containing a trace or strap, O, as

thick as ever required to be acted on, as vindicated in Fig. 3.

To use the instrument a portion of the trace or strap to be creased islaid in the die A,and the end of the creasing-tool B is moved forwardand backward laterally over it repeatedly with suicient pressure tocrease or shape the same permanently 5 then another portion of the traceor strap is drawn along into the die and treated as before till thewhole is completed.

The advantages of this device for creasing or shaping leather are notmerely its simplicity and cheapness, but the work done by it is muchmore perfect and permanent than when done between rollers, since therepeated rubbin gs forward and backward with pressure produce much morethorough work than by simple compressiononce applied; and the leatherbeing held in a straight position, while undergoing the operation, isthereby left in better shape than when supported only at `the line ofcontact between rollers.

Fig. 4 shows a trace stuffed in its grooved surface ush with theremainder of the surface on that side, strip, d, of leather.

The operation of the tool B over the die A may be effected by machinery.

What I claim as my invention, and desire to secure by Letters Patent, isv The combination ofthe die A and creasingtool B, constructed andoperating substantially as and for the purpose herein specified.

Specification signed by me this 8th day of February, 1872.
